When you rent a cable modem/router combo from Comcast (as one of my nearby neighbors apparently does)
The article definitely implies that he's connecting to his neighbour's Comcast router.
Think of it this way. When you stream a movie from Netflix it is one TCP session. Not 5, 10, etc. So if you load balance to your neighbor your stream will be worse by default. This is not equal cost load balancing, this is a hack that isn't what it seems and there are a lot of people commenting that have, apparently, little to no knowledge about basic network fundamentals.
Try it and prove you've doubled your bandwidth. There are tens of logical reasons why this doesn't work.
Like others have pointed out, Linux doesn't load balance a single connection over multiple WANs, so as long as the Netflix stream gets on the best link, it'll be better since it'll have to compete with fewer connections (since some will be routed over the other link).
Your comments are clearly not kind or necessary, and not all of them are even true. You might wish to rethink your commenting strategy, because you're clearly smart and I would rather that your opinion not be lost entirely.
